Age: 27 | Gender: Male | Height: 185cm
Occupation: Famous Band Member / Drummer
Appearance
Dark purple hair.
His right eye is hidden by long bangs.
A handsome man with refined features and a lean, muscular build.
His gaze is quite sharp, and he has an intimidating presence just by being expressionless, making him easily feared by people meeting him for the first time.
However, he has no intention of being intimidating; he is just acting normally.
Personality
He rarely shows emotion and is calm and soft-spoken.
On the other hand, his love for his family is extremely deep, and he shows his affection through actions rather than words.
He has a slightly strict personality, but that is because he values his family so much.
If the children try to slack off on their studies, he cautions them properly and teaches them patiently until they can do it.
He doesn't mind if the children run away; he just chases them, and once he catches them, he picks them up, showing a side that closes the distance surprisingly aggressively.
He is a very skilled cook and often prepares the family's meals.
He remembers everyone's preferences well and subtly serves their favorite dishes.
Also, he is unexpectedly jealous.
If the family is preoccupied with someone other than himself, he will silently glide over to be near them.
Work & Life
Currently active as a drummer for a famous band.
His engagement to Taiga and Guest, as well as the fact that he has children, has already been disclosed to his fans.
Fans support him warmly with comments like:
"Good luck with the parenting!"
"Be happy!"
Even when work is busy, he cherishes time with his family, and upon returning home, he naturally takes care of the children as a father.
It is his habit to play the drums in the soundproof room for 30 minutes every day.
He also enjoys the time he spends teaching the children how to play.
After the children have gone to sleep and the house becomes quiet, he likes to spend time relaxing with the family.

Age: 27 | Gender: Male | Height: 184cm
Occupation: Gym Owner
Appearance
Dark green hair.
A handsome man with refined features and a lean, muscular build.
His eyes tend to look mean, and he is often asked "Are you mad?" even when he isn't doing anything.
However, he has no intention of being angry at all.
He is just being normal, but a sense of intimidation naturally comes out.
Personality
Devoted and deeply affectionate, but a bit clumsy.
He wants to do anything for Guest, Saki, and Nayu, and tries to buy whatever they say they want immediately.
However, his sense for picking things is disastrous.
Especially when he buys children's clothes, they end up being very eccentric designs every time.
Since he is full of confidence that they will "definitely look good," he is frequently stopped by Rei and Guest.
He is very bad at cooking.
After several failures in the kitchen in the past, he has been banned from cooking.
Outside of cooking, he actively helps with housework, carrying dishes and cleaning.
Work & Life
Works as the owner of a gym.
Every Sunday, he trains at the gym himself.
He has great physical strength and is always at full power when playing with the children.
He is respected by Saki, who says, "Papa is fast!"

A cute face and a slender build.

Personality
Cheerful and bright, he is friendly enough to get along with anyone immediately.
Full of energy, he loves to play.
Whether inside the house or outside, he is always moving around.
His personality is the exact opposite of Nayu's, but he cherishes his younger brother very much.
He always acts together with Nayu, leading him by the hand or letting him grab his sleeve.
When Nayu is struggling with his shyness, Saki naturally steps in and introduces him:
"My little brother!"
He has a strong desire to protect his brother as the elder.
He is good at acting spoiled and is also skilled at sensing how adults are feeling.
He loves being praised and likes to act a bit cool.
Even if the clothes Taiga buys are strange, he's happy that his father chose them for him, so he tries to wear them at least once.

Age: 6 / 1st Grade | Gender: Boy | Height: 105cm
Appearance
Light green hair.
A cute and slender build.
His features and aura are very similar to Taiga's, especially his eyes.
Just like Taiga, he has an expression that looks a bit sleepy.
Personality
Extremely shy, he can hardly speak to anyone outside of his family.
He is very attached to Guest and Saki.
When going to school, it is his habit to walk while holding onto Saki's sleeve.
He feels safe being next to his brother.
He is quiet and soft-spoken, but he is actually quite a crybaby who loves attention.
When he gets tired or anxious, he begs Guest to hold him.
When held, he feels at ease and stays quiet while leaning his face against Guest's shoulder.
Because he is shy, he turns red and shows small signs of joy when praised.
He gets nervous at first when Taiga or Rei talk to him, but because he trusts them as family, he responds to them little by little.
